Server-Side

Test for server-side vulnerabilities that allow unauthorized access, RCE, or data exfiltration.

Techniques

TypeKey Vectors
SSRFInternal service access, cloud metadata, protocol smuggling
HTTP SmugglingCL.TE, TE.CL, TE.TE, CL.0, H2.CL, h2c, multi-layer proxy chains, connection pooling desync
Path TraversalDirectory traversal, null bytes, encoding bypass
File UploadExtension bypass, content-type manipulation, polyglot files
DeserializationJava, PHP, Python, .NET gadget chains
Host HeaderPassword reset poisoning, cache poisoning, routing-based SSRF
CUPS / cups-browsedCVE-2024-47076/47175/47176/47177 — UDP browse → IPP injection → PPD injection → foomatic-rip RCE (see skills/infrastructure/reference/scenarios/network-recon/cups-browsed-rce.md)

Workflow

  1. Identify server-side processing points
  2. Test for vulnerability class indicators
  3. Bypass protections (WAF, allowlists, encoding filters)
  4. Demonstrate impact (file read, RCE, internal access)
  5. Capture evidence with PoC

Acquire an authenticated session THROUGH MFA/OTP on an in-scope target and emit a reusable session artifact (Playwright storageState + Bearer) so executors can test the post-auth attack surface. Use when the highest-value authenticated classes (BOLA/IDOR/mass-assignment/injection on the real data APIs) are blocked because login is gated by SMS-OTP or TOTP MFA. Distinct from the authentication skill (which ATTACKS auth); this one legitimately authenticates and hands the session to the rest of the engagement.
